The U.S. believes the Chinese government was behind an internet hacking attack on Google and Western governments.

Beijing has adamantly denied any knowledge of the internet interference.

But secret U.S. diplomatic cables released by Wikileaks quote an official from the American Embassy in Beijing as saying that a contact blamed the Chinese authorities.

‘The Google hacking was part of a coordinated campaign of computer sabotage carried out by government operatives, private security experts and Internet outlaws recruited by the Chinese government,’ said the ‘Chinese contact’.

Chinese operatives are also believed to have broken into computers of U.S. and Western allies along with those of Tibet’s exiled spiritual leader the Dalai Lama, the cables said, according to the New York Times.
